Want to contribute to Free Software development? Advanced users are needed to test the new beta release of Cura2 LulzBot Edition! New features include an updated user interface, more slicing options in the Cura2 slicing engine, and better print quality than ever before.

Advanced users can help by using the new slicing profiles, trying out the new features, and testing your workflow in the new interface. More importantly, we’d love to hear your feedback!

New users are STRONGLY encouraged to use Cura(1) LulzBot Edition

Ready to get started? Visit LulzBot.com/Cura to download the Cura2 install packages for your operating system. The latest Cura2 Beta version will be listed there and announced in this thread.

Some say all Windows updates must be installed first before manually installing MS Visual C++ 2015 Redistributable. Others say no updates, or perhaps only specific ones are required. Will try to follow up if I can get it working.

Under the current setup if you have the dually activated in the software, you can only dual print two materials. For instance abs & ninjaflex.
In old software you could avoid this problem if you use a single filament profile and insert “T1” in the processed gcode. But you still need to make sure your using a pretty small model, because everything will be off by 50mm. (Serious limitation for bigger models)

For new Software please

add single extrusion of front extruder flexdually in software (T1 only not added)

separate settings for both filaments (added)

If user only wants to print with front flex extruder, hide or grey out solid filament. Then after gcode is processed:
Heat up both extruders for wipe
Use back extruder for auto level calibration.
Cool down back extruder
Account for the offset of using the front extruder instead of back extruder in gcode.
Begin print.

I would love if you guys added the ability to use the flexdually front extruder only. There are times when you only need to print a flexible model, this is not possible in old or new software. Say you need feet for the bottom of a model to keep it from moving or a gasket to make something air or water tight.

Left hand side of the screen below scale and multiply options, you have print with extruder 1 or 2. I just tried putting everything to extruder 2 without an issue. Ill have to look over the gcode and make sure its right later. I do see the correct .6mm nozzle for tool 1 and .4 for tool 0.

The issue I have is the over constrained print area. Only the rear should be limited, not the front on the y axis. Both nozzles can reach over the entire front section. This cuts the build area down way too much.

Ive been trying for days to just export the sliced model and have gotten nowhere.
Im using the latest beta on Mac with Sierra 10.12.6. The software constantly hangs while slicing, wether i set it to auto slice or not. all exported files come out blank. no .gcode to check for errors. When I view the object and try to view layers and tool paths I just see a solid object. Everything in the program looks great and all the features look awesome, just wish more was working on my machine so I could test some prints.

Things I really hope are available soon are:
USB Printing
Ability to print supports with dual extruders (PLA supports for Ninjaflex object)
Better view modes (I can only see the object core as a solid, and the shell. No tool path, layers, or supports yet)
Im loving the interface for adding filament profiles and all the options there.

Hope a working version of the beta is up soon. Even if it is only working enough to allow me to export gcode that would be fine with me.

I’ve been playing with ver 2.6.21. It does have the view models you seek, but they aren’t default. However easy as a pull down menu. What you seek is:
under view mode
select layers. (what u saw).
But then change color scheme from material color to line type
which shows:
extruder 1
extruder 2
show travels
shows helpers (support material)
show shell
show infill

I personally love how the outline of the model is grayed well viewing the layers.

But the octoprint integration is one of the new killer features.
You can:
Save and or print directly to your octoprint server without going to a browser.
Connect, Disconnect, pause, abort octoprint from within the Cura.
Preheat, extrude, control the printer via octoprint but without leaving app
View the octroprint cam directly in Cura without going to a web broswer.
Awesome sauce.

I’ve seen a couple people ask in this thread and others about using pla or abs as a support for flexible material in Cura. Seems everyone is having trouble getting it to work.
Anyway found this video on YouTube, he prints a dog with a pla core and bronzefill shell over the dog as the skin. I don’t see why those looking to do the same with pla core and ninjaflex couldn’t copy and adapt his technique.https://youtu.be/b1Unrmf-JAg
Maybe someone could try it.

The video also shows Cura 2.6 can do custom supports but it’s not as easy as simplify3d.

I still cant get the darn thing to generate .gcode to print with the Legacy version. Keeps telling me to update my firmware because Ive switched nozzles, and the slicing generator just keeps slicing, never stops. Tried to submit bug reports on phabricator but thats like trying to fill out tax documents to become a nonprofit.

Sorry your having so many issues. It works fine for me.
My issue is quality. Profiles aren’t tuned for the flexdually 0.6 nozzle. So Im having to tweak settings to get quality prints, and supports that separate easier. I don’t mind doing it, I knew that going in, it’s a beta. The improvement in Cura is well worth it. It’s miles ahead of standard our current version.

Maybe try reinstalling. I did notice another version in lulzbots download section - 2.6.20 is now 2.6.21.

I downloaded and ran the latest version. Windows.
I selected Mini, and continue.
I got this message and canceled. I did not change the print head. Any ideas why this popped up, and how to proceed? It seems like a pretty stern warning.
Thanks!

Never seen that error before.
Prusa slic3er edition loaded it, and sliced it.

Simplify3d loaded it, and sliced it.

Cura 21.04 took a while to load and render the model. While also taking a full 5 mins to compute gcode for any single change. So while being barely able to load the .stl its completely unusable for making print parameter changes.

However I’ve found a problem with changing profiles.
Have your 3 profiles - High detail, High speed and Standard. For me its stuck on High detail 0.18mm. I can not choose a different profile and have to layer height be reflected by different choice. The layer height remains on 0.18mm for high detail, no matter which profile I try to choose.

How does one split a grouped model into separate pieces with this version?

In Cura 21.04 called its “Split object into parts”

Its a super useful tool for when a designer has grouped a bunch models together but you only need 1 part printed. Or maybe 1 or 2 of the grouped items isn’t touching the build plate like in the .stl i’ll post. This model is the dragons tail and waist from thingiverse, its very popular and challenging to print. (Turn on the brim and view layer lines in cura 21.04. You’ll see all models in group do not touch build plate)
Cura 2.6.29 seems to be adjusting each model in the group to the build plate automatically, although I haven’t verified with a print. I still would like to be able to separate parts of a whole.

In Cura 21.04 I had to:
I had to split the neck group into several smaller groups.
Pieces that touched build plate as designed - delete others
Pieces that needed to be moved down by .5mm - delete others
Pieces that needed to be moved down by 1mm - delete others.
